Details of the Ball Mill Bearing Mechanism

In the design of ball bearing means , not only to take into account the mill capable of continuous operation , trying to reduce the power consumption due to the friction between the shaft and the hollow sphere watts generated , but also to prevent dust from entering them.

Work characteristics ball bearing devices:

First, the heavy load to bear , and has a certain vibration ;

Second, the low speed of the hollow shaft ; Third, poor working conditions mill , dusty .

In general, the main bearing mill has two Rolling and plain bearings . Limited Rolling mill can be applied on a small , but do not use a large mill Rolling reason is its high cost of processing a single piece , and bearing with part machining accuracy requirements are high , bearing installation and maintenance more difficult, and the service life of rolling bearings and requires filtering and cooling oil circulation system .

Sliding ball bearings , according to their structure, can be divided into two types with hollow journal bearing main bearings and sliding shoe . Generally bearing, bearing pedestal , bearing caps , lubrication and cooling system. Which is characterized by large size, heavy weight to bear heavy load , the use of self-aligning spherical device can ensure the straightness of the mill .

In addition, both ends or one end of the mill is not usually the main bearing , instead of using the sliding shoe bearing . The advantage is to support the grinding wheel with the shoe can have two , three or four , so the structure is not only suitable for small mill completely and without specification limit , the large mill can also be used.
